Paul, the smoke is from the motor swap. Typical fluid leaks burning off. Probably from Pdad dousing the rear bank of the valvetrain after he installed it (oil and cam/lifter prelube).
Eric, the valvecovers are F-body aluminum valvecovers with wrinkle coating to dissipate heat like the SC. Laser engraving as well, of course.
Intercooler isn't hooked up yet. Wiring and plumbing will be today, and will be covered in Performance and Brainstorming.
Work on Pdad'* car never happened. His needle bearing grease and TB adapter never arrived in time. Irony wil prevail, and they'll arrive today.
I still have all parts here, so I can match the adapter to the GenV, and build the SC. Pdad and Pmom will make another trip down soon for the install, and some pre-arranged work underneath by my local exhaust guy.
Vid of the startup (had been running about 10 seconds). Fired on the first crank, no lifter clatter at all (these are the lifters from the donor Riviera motor).
